The Document Lens recognises and extracts entities from text files in the PDF, DOCX, and TXT formats. Based on a scalable Natural Language Processing pipeline, the Lens can be easily configured to retrieve entities belonging to a multi-domain knowledge graph or any dataset accessible via a SPARQL endpoint. With provenance as standard, this lightweight, highly-scalable, platform-agnostic tool has support for all the common Knowledge Graphs and generic SPARQL support for the less common.
